e12a4f6ec8 Revert "thread: add spdk_env_get_primary_core"
This reverts commit 6194cb2e15.

It's unclear whether we need to add a new API for the env layer
for upcoming work. Nothing currently uses it. When we have a clear
need, we can add this back in.

ab12e36be6 env: drop DPDK 16.07 support
Now that even DPDK 16.11 (LTS) reaches its end of life in
November 2018, we can surely drop support for DPDK
versions older than that.

The PCI code will go through a major refactor soon, so this
patch cleans it up first.

Since this is the very first SPDK patch that drops support
for older DPDK versions, it also introduces an #error
directive that'll directly fail the build if the used DPDK
lib is too old.

33ccbba438 env/dpdk: add security checks to spdk_env_get_socket_id()
The underlying DPDK function we use reads an array
at the provided index without checking for any out
of bounds access. The array is RTE_MAX_LCORE elements
long, so always manually check against that to keep
our APIs safe.

This fixes potential crashes with lcore == SPDK_ENV_LCORE_ID_ANY

2b8c23c7b8 env: make spdk_env_get_last_core() thread safe
Previously, the maximum core value was cached in a static variable, but
this isn't safe if multiple threads are calling at the same time.

Iterating over all core numbers is not very expensive, so just
recalculate the value for every call.
